I'm really not sure what the best way is to replicate this, but this might be one way. Using the Pathfinder sheet Start a game, create a character, in the classes tab give it some HP and 1 level. Verify that the character has a max hp in the core tab. Create a token for the character, set bar 3 to HP, it should populate the max with the total from the sheet. Populate the "current" box with the same number as the max. Link the token and set it as a default. Verify that you can see a full red bar above the character. Exit the game and open it again. Notice that the character does not have an HP bar on it anymore. The current workaround to make it appear again is to just open the token and save it, or update the HP.
